Wittekoek et al. proposed in a purely qualitative manner that the origin of the large Faraday rotation in Bi,Pb-substituted iron garnets is the hybridization of Bi,Pb 6p orbitals, which possess anomalously large spin-orbit coupling (ζ 6 p ≈ 2 eV), with the O 2p and Fe 3d orbitals. Quantum-chemistry chemical-kinetics electronic-structure molecular-modeling nonadiabatic spin-orbit-coupling. Updated on Feb 24. Fortran. spin-orbit-coupling topic page so that developers can more easily learn about it. To associate your repository with the spin-orbit-coupling. In this scenario, jj-coupling is a more appropriate way of describing the effects of spin-orbit coupling on the electronic state. On the other hand, if the spin-orbit coupling is relatively small, then $\vec{L}$ and $\vec{S}$ are useful quantities which are still applicable to the atom's electronic state, so the Russell–Saunders scheme is.
